This prospectus relates to the resale from time to time of up to 2,221,880 shares of common stock, par value $0.001 per share (the “Common Stock”), of BIOLASE, Inc. issuable upon exercise of outstanding warrants (the “Common Warrants”) purchased by the selling stockholder identified in this prospectus (the “Selling Stockholder”), including its pledgees, assignees, donees, transferees or their respective successors-in-interest in a private placement transaction that closed on December 8, 2023 (the “Private Placement”). The shares of Common Stock issuable upon exercise of the Common Warrants are sometimes referred to as the “Common Warrant Shares.”

We are filing the registration statement on Form S-1, of which this prospectus forms a part, to fulfill our contractual obligations with the Selling Stockholder to provide for the resale by the Selling Stockholder of the shares of Common Stock offered hereby. See “Selling Stockholder” beginning on page 28 of this prospectus for more information about the Selling Stockholder. The registration of the shares of Common Stock to which this prospectus relates does not require the Selling Stockholder to sell any of their shares of our Common Stock.

We are not offering any shares of Common Stock under this prospectus and will not receive any proceeds from the sale or other disposition of the shares of our Common Stock covered hereby. See “Use of Proceeds” beginning on page 8 of this prospectus.

The Selling Stockholder identified in this prospectus, or its pledgees, assignees, donees, transferees or their respective successors-in-interest, from time to time may offer and sell through public or private transactions at prevailing market prices, at prices related to prevailing market prices or at privately negotiated prices the shares held by them directly or through underwriters, agents or broker-dealers on terms to be determined at the time of sale, as described in more detail in this prospectus. See “Plan of Distribution” beginning on page 30 of this prospectus for more information about how the Selling Stockholder may sell their respective shares of Common Stock. The Selling Stockholder may be deemed “underwriters” within the meaning of Section 2(a)(11) of the Securities Act of 1933, as amended (the “Securities Act”).

In connection with the Private Placement, we have agreed, pursuant to a securities purchase agreement, dated December 8, 2023, that we have entered into with the Selling Stockholder, to bear all of the expenses in connection with the registration of the Common Warrant Shares pursuant to this prospectus. The Selling Stockholder will pay or assume all commissions, discounts, fees of underwriters, agents, selling brokers or dealer managers and similar expenses, if any, attributable to their respective sales of the shares of Common Stock.

Our Common Stock is listed on the Nasdaq Capital Market under the symbol “BIOL.” On December 22, 2023, the closing price of our Common Stock on the Nasdaq Capital Market was $1.16 per share.

Investing in our Common Stock involves risks. You should review carefully the risks and uncertainties described under the heading “Risk Factors” contained in this prospectus and under similar headings in the other documents that are incorporated by reference into this prospectus, as described beginning on page 7 of this prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus.

We have relied on certain data from third-party sources, including internal surveys, industry forecasts and market research, which we believe to be reliable based on our management’s knowledge of the industry. Forecasts are particularly likely to be inaccurate, especially over long periods of time.

PROSPECTUS SUMMARY

This summary contains basic information about us and this offering. Because it is a summary, it does not contain all of the information that you should consider before deciding to invest in our securities. Before you decide to invest in our securities, you should read this entire prospectus carefully, any related free writing prospectus that we have authorized for use in connection with the offering and the documents incorporated by reference herein, including the information included under the heading titled “Risk Factors.” Unless otherwise noted, all share and per share information relating to our Common Stock in this prospectus has been adjusted to reflect the 1-for-100 2023 Reverse Stock Split (as defined below) effected on July 27, 2023.

Our Company

BIOLASE, Inc. (“BIOLASE” and, together with its consolidated subsidiaries, the “Company,” “we,” “our” or “us”) is a leading provider of advanced laser systems for the dental industry. We develop, manufacture, market, and sell laser systems that provide significant benefits for dental practitioners and their patients. Our proprietary systems allow dentists, periodontists, endodontists, pediatric dentists, oral surgeons, and other dental specialists to perform a broad range of minimally invasive dental procedures, including cosmetic, restorative, and complex surgical applications. Our laser systems are designed to provide clinically superior results for many types of dental procedures compared to those achieved with drills, scalpels, and other conventional instruments. Potential patient benefits include less pain, fewer shots, faster healing, decreased fear and anxiety, and fewer appointments. Potential practitioner benefits include improved patient care and the ability to perform a higher volume and wider variety of procedures.

We offer two categories of laser system products: Waterlase (all-tissue) systems and diode (soft-tissue) systems. Our flagship brand, the Waterlase, uses a patented combination of water and laser energy and is FDA cleared for over 80 clinical indications to perform most procedures currently performed using drills, scalpels, and other traditional dental instruments for cutting soft and hard tissue. For example, Waterlase safely debrides implants without damaging or significantly affecting surface temperature and is an effective, safe solution for preserving sick implants. In addition, Waterlase disinfects root canals more efficiently than some traditional chemical methods. We offer our diode laser systems to perform soft tissue, pain therapy, and cosmetic procedures, including teeth whitening. As of December 31, 2022 we maintained approximately 259 active and 24 pending United States and international patents, with the majority relating to our Waterlase technology. Our patent portfolio is regularly evaluated, and we strategically prioritize our core patents to ensure optimal intellectual property coverage while minimizing annual maintenance fees. From 1998 through December 31, 2022, we have sold over 45,500 laser systems in over 80 countries around the world, and we believe that Waterlase iPlus is the world’s best-selling all-tissue dental laser. Since 1998, we have been the global leading innovator, manufacturer, and marketer of dental laser systems.

Our Waterlase systems precisely cut hard tissue, bone, and soft tissue with minimal or no damage to surrounding tissue and dental structures. Our diode systems, which include the Epic system, are designed to complement our Waterlase systems and are used only in soft tissue procedures, pain therapy, hygiene, and cosmetic applications, including teeth whitening. The diode systems, together with our Waterlase systems, offer practitioners a broad product line with a range of features and price points.

We also manufacture and sell consumable products and accessories for our laser systems. Our Waterlase and diode systems use disposable laser tips of differing sizes and shapes, depending on the procedure being performed. We also market flexible fibers and hand pieces that dental practitioners replace at some point after initially purchasing laser systems. For our Epic line of diode laser systems, we sell teeth whitening gel kits.

Due to the limitations associated with traditional and alternative dental instruments, we believe there is a large market opportunity for all-tissue dental laser systems that provide superior clinical outcomes, reduce the need to

use anesthesia, help reduce trauma, pain, and discomfort associated with dental procedures, and increase patient acceptance for treatment protocols.

Business Strategy and Outlook

Our strategy is to increase awareness and demand for (i) our products among dental practitioners by educating dental practitioners and patients about the clinical benefits of our product suite and (ii) our laser systems among patients by educating patients about the clinical benefits of the Waterlase and diode systems. An important goal of ours is to increase consumables revenue by selling more single-use accessories used by dental practitioners when performing procedures using our dental laser systems. In the short term, we are striving for operating excellence through lean enterprise initiatives, with a specific focus on our sales strategy and cash flow management, coupled with optimizing our engineering capabilities to develop innovative new products.

We also seek to create value through innovation and leveraging existing technologies into adjacent medical applications. We plan to expand our product line and clinical applications by developing enhancements and transformational innovations, including new clinical solutions for dental applications and for other adjacent medical applications. In particular, we believe that our existing technologies can provide significant improvements over existing standards of care in fields including ophthalmology, otolaryngology, orthopedics, podiatry, pain management, aesthetics/dermatology, veterinary, and consumer products. We plan to continue to explore potential collaborations to apply our proprietary laser technologies with expanded FDA-cleared indications to other medical applications in the future.

For additional information about our Company, please refer to other documents we have filed with the SEC and that are incorporated by reference into this prospectus, as listed under the heading “Incorporation of Certain Information by Reference.”

Recent Developments

Registered Direct Offering and Concurrent Private Placement

On December 6, 2023, we entered into a Securities Purchase Agreement (the “Purchase Agreement”) with a single institutional investor (the “Purchaser”, which is also the Selling Stockholder), pursuant to which we issued to the Purchaser, (i) in a registered direct offering, 331,000 shares (the “Shares”) of our Common Stock and pre-funded warrants to purchase 779,940 shares of Common Stock (the “Pre-Funded Warrants”) with an exercise price of $0.001 per share, and (ii) in a concurrent Private Placement, the Common Warrants to purchase up to 2,221,880 Common Warrant Shares with an exercise price of $1.23 per share. Such registered direct offering and concurrent Private Placement are referred to herein as the “Transactions.” The combined purchase price for one share of Common Stock and two Common Warrants was $1.23, and the combined purchase price for one Pre-Funded Warrant and two Common Warrants was $1.229.

We received aggregate gross proceeds from the Transactions of approximately $1.4 million, before deducting fees to the Placement Agent (as defined below) and other estimated offering expenses payable by us. The Shares, the Pre-Funded Warrants and the shares of Common Stock issuable upon exercise of the Pre-Funded Warrants (the “Pre-Funded Warrant Shares”) were offered by us pursuant to a shelf registration statement on Form S-3 (File No. 333-266852), which was declared effective on August 24, 2022. The Common Warrants and the Common Warrant Shares issued in the Private Placement were not registered under the Securities Act. Rather the Common Warrants and the Common Warrant Shares were issued pursuant to the exemption from registration provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder. The Common Warrants are exercisable commencing on the effective date of stockholder approval for the issuance of the shares of our Common Stock issuable upon exercise of the Common Warrants (the “Stockholder Approval Date”) and will expire on the fifth anniversary of the Stockholder Approval Date. The Pre-Funded Warrants were

immediately exercisable upon issuance and may be exercised at any time until all of the Pre-Funded Warrants are exercised in full.

Pursuant to the Purchase Agreement, we agreed to file a registration statement to register the resale of the Common Warrant Shares within 30 days of the date of the Purchase Agreement and to use commercially reasonable efforts to cause such registration statement to become effective within 121 days following the closing of the Transactions (or within 181 days following the closing of the Transactions if the SEC informs us that it intends to review such registration statement). The registration statement on Form S-1, of which this prospectus forms a part, is being filed to satisfy the requirement set forth in the Purchase Agreement to register for resale the Common Warrant Shares. The Purchaser has agreed not to resell or distribute the Common Warrants or the Common Warrant Shares to the public except pursuant to an effective registration statement under the Securities Act or an exemption therefrom.

Maxim Group LLC acted as the placement agent (the “Placement Agent”) on a “reasonable best efforts” basis, in connection with the Transactions pursuant to that certain Placement Agency Agreement, dated December 6, 2023 (the “Placement Agency Agreement”), by and between us and the Placement Agent. Pursuant to the Placement Agency Agreement, the Placement Agent was entitled to a cash fee of 7% of the aggregate gross proceeds paid to us for the securities sold in the Transactions and reimbursement of certain out-of-pocket expenses.

See “Description of the Private Placement” on page 26 of this prospectus for a more detailed description of the Private Placement and the Transactions.

Smaller Reporting Company

We are currently a “smaller reporting company,” meaning that we are not an investment company, an asset-backed issuer, or a majority-owned subsidiary of a parent company that is not a smaller reporting company, and have a public float of less than $250 million or annual revenues of less than $100 million during the most recently completed fiscal year. As a result of being considered a “smaller reporting company,” we will be entitled to certain exemptions regarding the disclosure that we are required to provide in our SEC filings. Specifically, “smaller reporting companies” are able to provide simplified executive compensation disclosures in their filings; are exempt from the provisions of Section 404(b) of Sarbanes-Oxley requiring that independent registered public accounting firms provide an attestation report on the effectiveness of internal control over financial reporting; and have certain other decreased disclosure obligations in their SEC filings, including, among other things, only being required to provide two years of audited financial statements in annual reports. Decreased disclosures in our SEC filings due to our status as a “smaller reporting company” may make it harder for investors to analyze our results of operations and financial prospects.

Summary of the Material and Other Risks Associated with Our Business

Our business is subject to numerous material and other risks and uncertainties that you should be aware of in evaluating our business. In particular, you should carefully consider the following risks, which are discussed more fully in the section entitled “Risk Factors” in this prospectus and the documents incorporated by reference in this prospectus:

•

You may experience future dilution as a result of the exercise of the Common Warrants, future equity offerings and other issuances of our Common Stock or other securities.

•

The market price of our Common Stock may be volatile and may fluctuate in a way that is disproportionate to our operating performance.

•

The COVID-19 pandemic has adversely affected, and may continue to adversely affect, our business, results of operations and financial condition.

•

There is substantial doubt about our ability to continue as a going concern due to our accumulated deficit, recurring and negative cash flow from operations.

•

We have experienced net losses for each of the past several years, and we could experience additional losses and have difficulty achieving profitability in the future.

•

We may need to raise additional capital in the future, and if we are unable to secure adequate funds on terms acceptable to us, we could be unable to execute our business plan.

•

Dentists and patients have been hesitant in adopting laser technologies, and our inability to overcome this hesitation could limit the market acceptance of our products and our market share.

•

Any failure in our efforts to train dental practitioners could result in the misuse of our products, reduce the market acceptance of our products and have a material adverse effect on our business, financial condition, and results of operations.

•

If future data proves to be inconsistent with our clinical results or if competitors’ products present more favorable results, our revenues could decline and our business, financial condition and results of operations could be materially and adversely affected.

•

We could be subject to significant warranty obligations if our products are defective, which could have a material adverse effect on our business, financial condition, and results of operations.

•

Product liability claims against us could be costly and could harm our reputation.

•

Our manufacturing operations are consolidated primarily in one facility. A disruption at this facility could result in a prolonged interruption of our business and have a material adverse effect on our business, financial condition and results of operations.

•

If third parties claim that we infringe their intellectual property rights, we could incur liabilities and costs and have to redesign or discontinue selling certain products, which could have a material adverse effect on our business, financial condition, and results of operations.

•

Changes in government regulation, failure to comply with government regulation or the inability to obtain or maintain necessary government approvals could have a material adverse effect on our business, financial condition, and results of operations.

•

Our products are subject to recalls and other regulatory actions after receiving FDA clearance or approval.

•

Failure to meet Nasdaq’s continued listing requirements could result in the delisting of our Common Stock, negatively impact the price of our Common Stock and negatively impact our ability to raise additional capital.

•

The trading price of our Common Stock price has been, and could continue to be, volatile.

Common Stock

Voting Rights. Holders of our common stock are entitled to one vote per share. Except as required by the DGCL, our Charter or our Bylaws, matters will generally be decided by the affirmative vote of the holders of a majority in voting power of the shares of capital stock present in person or represented by proxy at a meeting and entitled to vote on the subject matter. Our Bylaws provide that each of our directors is elected by the affirmative vote of a majority of the votes cast with respect to such director in uncontested elections. In a contested election, each of our directors is elected by an affirmative vote of a plurality of the votes cast by the shares represented and entitled to vote with respect to the election of such director. A “contested election” is defined in our Bylaws as an election with respect to which, as of the record date for the meeting at which directors are to be elected, the number of nominees exceeds the number of directors to be elected at such meeting. Vacancies on our Board may be filled by an affirmative vote of two-thirds of the remaining members of our Board or at a meeting of the stockholders in the manner set forth above.

Dividend Rights. Subject to any preferential rights of any outstanding shares of our preferred stock to receive dividends before any dividends may be paid on our common stock, the holders of our common stock will be entitled to share ratably in any dividends that may be declared by our Board out of funds legally available for the payment of dividends. Our ability to pay dividends on our common stock will be limited by restrictions on our ability to pay dividends or make distributions to our stockholders and on the ability of our subsidiaries to pay dividends or make distributions to us, in each case, under the terms of our current, and any future, agreements governing our indebtedness.

Other Rights. Each holder of our common stock is subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock that our Board may designate and we may issue in the future. Holders of our common stock have no preemptive, conversion or other rights to subscribe for additional shares. Our common stock does not carry any redemption rights or any preemptive rights enabling a holder to subscribe for, or receive shares of, any class of our common stock or any other securities convertible into shares of any class of our common stock.

Liquidation Rights. Subject to any preferential rights of any outstanding shares of our preferred stock, in the event of our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in the assets remaining after payment of liabilities and the liquidation preferences of any outstanding preferred stock.

Standstill Agreements. Pursuant to (1) a standstill agreement with Jack W. Schuler, Renate Schuler and the Schuler Family Foundation (collectively, the “Schuler Parties”), dated November 10, 2015 (as amended on August 1, 2016 and November 9, 2017, the “Schuler Standstill Agreement”), and (2) a standstill agreement with Larry N. Feinberg, Oracle Partners, L.P., Oracle Institutional Partners, L.P., Oracle Ten Fund Master, L.P., Oracle Associates, LLC and Oracle Investment Management, Inc. (collectively, the “Oracle Parties”) dated November 10, 2015 (as amended on August 1, 2016 and November 9, 2017, the “Oracle Standstill Agreement” and, together with the Schuler Standstill Agreement, the “Standstill Agreements”), each of the Schuler Parties and the Oracle Parties agreed with respect to itself and its associates and affiliates (i) not to purchase or acquire any shares of our common stock if such a purchase would result in aggregate beneficial ownership by it and its affiliates and associates in excess of 41% of the issued and outstanding shares of our common stock and (ii) not to sell, transfer or otherwise convey shares of our common stock (or warrants or other rights to acquire shares of our common stock) to anyone who will immediately thereafter beneficially own shares in excess of 20% of the issued and outstanding shares of our common stock, as a result of such transfer and other transfers from third parties.

Preferred Stock

Our Charter authorizes our Board to provide for the issuance of shares of up to 1,000,000 shares of preferred stock in one or more series without further authorization from stockholders. Prior to issuance of shares of each series, our Board is required by the DGCL and our Charter to fix the designation, powers, preferences and rights of the shares of such series and the qualifications, limitations or restrictions thereof. As of December 15, 2023, we had: (i) 5,000 shares of Series H Convertible Preferred Stock outstanding (equal to 17,883 shares of our Common Stock issuable upon the conversion of these outstanding shares of Series H Convertible Preferred Stock), and (ii) 14,606 shares of Series J convertible Preferred Stock outstanding (equal to 448,037 shares of our Common Stock issuable upon the conversion of these outstanding shares of Series J Convertible Preferred Stock). No other shares of preferred stock were outstanding as of the date of this prospectus.

Series H Convertible Preferred Stock

Maturity. The Series H Convertible Preferred Stock matures two (2) years from the original issue date.

Ranking and Liquidation Preference. Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, prior and in preference to the common stock, holders of the Series H Convertible Preferred Stock shall be entitled to receive out of the assets available for distribution to stockholders an amount equal in cash to 100% of the aggregate stated value of $50.00 per share (the “Series H Stated Value”) of all shares of Series H Convertible Preferred Stock held by such holder, and any other fees then due and owing thereon under the certificate of designation establishing the Series H Convertible Preferred Stock (the “Series H Certificate of Designation”), and no more, and if the assets of the Company shall be insufficient to pay in full such amounts, then the entire assets to be distributed to the holders shall be ratably distributed among the holders in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full.

Dividends. The Series H Certificate of Designation provides that dividends on the Series H Convertible Preferred Stock shall be paid in-kind (“Series H PIK dividends”) in additional shares of Series H Convertible Preferred Stock based on the Series H Stated Value of $50.00 per share at the dividend rate of 20.0% (the “Series H Dividend Rate”). The Series H PIK dividends will be a one-time payment payable to holders of the Series H Convertible Preferred of record at the close of business on the one-year anniversary of the original issuance date (the “Series H Dividend Record Date”). Series H PIK dividends on each share of Series H Convertible Preferred Stock shall be paid three business days after the Series H Dividend Record Date in additional fully paid and nonassessable, registered shares of Series H Convertible Preferred Stock in a number equal to the quotient obtained by dividing (A) the product obtained by multiplying (i) the Series H Dividend Rate and (ii) the stated value of $50.00 per share, by (B) $26.00.

Conversion. The Series H Convertible Preferred Stock is convertible at any time at the option of the holder. Except as provided below, the Series H Convertible Preferred Stock is not convertible into or exchangeable for any other securities or property.

Conversion at Option of Holder. Each share of Series H Convertible Preferred Stock is convertible into shares of our common stock at the conversion price of $13.98 per share of our common stock (the “Series H Conversion Price”), which Series H Conversion Price is subject to adjustment and is based on the closing price of our common stock on May 23, 2023.

Holders shall effect conversions of the Series H Convertible Preferred Stock by providing us a conversion notice (a “Series H Notice of Conversion”), duly completed and executed. The Series H Notice of Conversion must specify the number of shares of Series H Convertible Preferred Stock then held by the holder and the number of such shares which the holder is converting. To effect conversions of shares of Series H Convertible Preferred Stock, a holder shall not be required to surrender the certificate(s), if any, representing the shares of Series H Convertible Preferred Stock to us unless all of the shares of Series H Convertible Preferred Stock represented thereby are so converted, in which case such holder shall deliver the certificate representing such shares of Series H Convertible Preferred Stock promptly following the conversion date at issue. Shares of Series H Convertible Preferred Stock converted into our shares of common stock shall be canceled and shall not be reissued.

If, at any time while the Series H Convertible Preferred Stock is outstanding: we (A) pay a stock dividend or otherwise make a distribution or distributions payable in shares of our common stock or any other Common Stock Equivalents (as defined in the Series H Certificate of Designation) (which, for avoidance of doubt, shall not include any shares of common stock issued by us upon conversion of the Series H Convertible Preferred Stock, or payment of a dividend on the Series H Convertible Preferred Stock) with respect to the then outstanding shares of common stock; (B) subdivide outstanding shares of common stock into a larger number of shares; (C) combine (including by way of a reverse stock split) outstanding shares of common stock into a smaller number of shares or (D) issue, in the event of a reclassification of shares of the common stock, any shares of our capital stock, which we refer to collectively as the “Anti-Dilution Provisions”, then the Series H Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of common stock (excluding any treasury shares) outstanding immediately before such event and of which the denominator shall be the number of shares of common stock outstanding immediately after such event (excluding any treasury shares). Any adjustment made as a result of the Anti-Dilution Provisions shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. All calculations will be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of the Anti-Dilution Provisions, the number of shares of common stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of common stock (excluding any treasury shares) issued and outstanding. Whenever the Series H Conversion Price is adjusted pursuant to any Anti-Dilution Provision, we will promptly deliver to each holder of Series H Convertible Preferred Stock a notice setting forth the Series H Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Notwithstanding the foregoing in no event may the Series H Conversion Price be less than the par value per share of Series H Convertible Preferred Stock.

Obligations Absolute. Subject to holder’s right to rescind a notice of conversion, our obligation to issue and deliver the shares of common stock upon conversion of Series H Convertible Preferred Stock in accordance with its terms are absolute and unconditional, irrespective of any action or inaction by a holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such holder or any other Person of any obligation to us or any violation or alleged violation of law by such holder or any other Person, and irrespective of any other circumstance which might otherwise limit our obligation to such holder in connection with the issuance of such shares of common stock. If we fail to deliver to a holder shares of common stock upon conversion by the Share Delivery Date (as defined in the Series H Certificate of Designation) applicable to such conversion, we shall pay to such holder, in cash, as liquidated damages and not as a penalty, for each $250 of Series H Stated Value of Series H Convertible Preferred Stock being converted, $2.50 per Trading Day (as defined in the Series H Certificate of Designation) (increasing to $5 per Trading Day on the third Trading Day after the Share Delivery Date and increasing to $10 per Trading Day on the sixth Trading Day after the Share Delivery Date) for each Trading Day after the Share Delivery Date until such Conversion Shares (as defined in the Series H Certificate of Designation) are delivered or holder rescinds such conversion.

Buy-In on Failure to Timely Deliver Certificates Upon Conversion. If we fail to deliver to a holder the applicable certificate or certificates or to effect a delivery via DWAC, as applicable, by the Share Delivery Date (other than a failure caused by incorrect or incomplete information provided by the holder to us), and if after such Share Delivery Date the holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the holder’s brokerage firm otherwise purchases, shares of common stock to deliver in satisfaction of a sale by such holder of the Conversion Shares which the holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then we are obligated to (A) pay in cash to the holder (in addition to any other remedies available to or elected by the holder) the amount by which (x) the holder’s total purchase price (including any brokerage commissions) for the shares of common stock so purchased exceeds (y) the product of (1) the aggregate number of shares of common stock that such holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of the holder, either reissue (if surrendered) the shares of Series H Convertible Preferred Stock equal to the number of shares of Series H Convertible Preferred Stock submitted for conversion or deliver to the holder the number of shares of common stock that would have been issued if we had timely complied with our delivery requirements. For example, if a holder purchases shares of common stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series H Convertible Preferred Stock with respect to which the actual sale price (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, we would be required to pay such holder $1,000. The holder shall provide us written notice, within three Trading Days after the occurrence of a Buy-In, indicating the amounts payable to such holder in respect of such Buy-In together with applicable confirmations and other evidence reasonably requested by us. Nothing herein shall limit a holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect our failure to timely deliver certificates representing shares of common stock upon conversion of the shares of Series H Convertible Preferred Stock as required pursuant to the terms hereof; provided, however, that the holder shall not be entitled to both (i) require the reissuance of the shares of Series H Convertible Preferred Stock submitted for conversion for which such conversion was not timely honored and (ii) receive the number of shares of common stock that would have been issued if we had timely complied with applicable delivery requirements.

outstanding shares of Series H Convertible Preferred Stock. We have further agreed that all shares of common stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid, nonassessable and free and clear of all liens and other encumbrances.

Beneficial Ownership Limitation. Notwithstanding anything herein to the contrary, we shall not effect any conversion of the Series H Convertible Preferred Stock, and a Holder shall not have the right to convert any portion of the Series H Convertible Preferred Stock, to the extent that, after giving effect to the conversion set forth on the applicable Series H Notice of Conversion, such Holder (together with such Holder’s Affiliates, and any Persons acting as a group together with such Holder or any of such Holder’s Affiliates (such Persons, “Series H Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of common stock beneficially owned by such Holder and its Affiliates and Series H Attribution Parties shall include the number of shares of common stock issuable upon conversion of the Series H Convertible Preferred Stock with respect to which such determination is being made, but shall exclude the number of shares of common stock which are issuable upon (i) conversion of the remaining, unconverted Series H Convertible Preferred Stock beneficially owned by such Holder or any of its Affiliates or Series H Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other of our securities subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Series H Convertible Preferred Stock) beneficially owned by such Holder or any of its Affiliates or Series H Attribution Parties. Except as set forth in the preceding sentence, for purposes of this section, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this section applies, the determination of whether the Series H Convertible Preferred Stock is convertible (in relation to other securities owned by such Holder together with any Affiliates and Series H Attribution Parties) and of how many shares of Series H Convertible Preferred Stock are convertible shall be in the sole discretion of such Holder, and the submission of a Series H Notice of Conversion shall be deemed to be such Holder’s determination of whether the shares of Series H Convertible Preferred Stock may be converted (in relation to other securities owned by such Holder together with any Affiliates and Series H Attribution Parties) and how many shares of the Series H Convertible Preferred Stock are convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to us each time it delivers a Series H Notice of Conversion that such Series H Notice of Conversion has not violated the restrictions set forth in this section and we shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this section, in determining the number of outstanding shares of common stock, a Holder may rely on the number of outstanding shares of common stock as stated in the most recent of the following: (i) our most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by us or (iii) a more recent written notice by us or the Transfer Agent setting forth the number of shares of common stock outstanding. Upon the written or oral request (which may be via email) of a Holder, we within one (1) Trading Day confirm orally and in writing to such Holder the number of shares of common stock then outstanding. In any case, the number of outstanding shares of common stock shall be determined after giving effect to the conversion or exercise of our securities, including the Series H Convertible Preferred Stock, by such Holder or its Affiliates or Series H Attribution Parties since the date as of which such number of outstanding shares of common stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, upon election by a Holder prior to the issuance of any shares of Series H Convertible Preferred Stock, 9.99%) of the number of shares of the common stock outstanding immediately after giving effect to the issuance of shares of common stock issuable upon conversion of Series H Convertible Preferred Stock held by the applicable Holder. A Holder, upon notice to us, may increase or decrease the Beneficial Ownership Limitation provisions of this section applicable to its Series H Convertible Preferred Stock; provided, that the Beneficial Ownership Limitation shall not in any event exceed 9.99% of the number of shares of the common stock outstanding immediately after giving effect to the issuance of shares of common stock upon conversion of this Series H Convertible Preferred Stock held by the Holder and the provisions of this section shall continue to apply. Any such increase will not be effective until the 61st day after such notice is delivered to

us and shall only apply to such Holder and no other Holder. The Beneficial Ownership Limitation shall not be waived by us or the Holder and upon issuance of the Series H Convertible Preferred Stock by us, and the purchase thereof by the Holder, each of us and the Holder shall be deemed to acknowledge such limitation and to agree not to waive it. The provisions of this section shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this section to correct this section (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this Section shall apply to a successor holder of Series H Convertible Preferred Stock.

Subsequent Rights Offerings. In addition to any Anti-Dilution Adjustments described above, if at any time we grant, issue or sell any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of common stock or any class thereof (the “Series H Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Series H Purchase Rights, the aggregate Series H Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of common stock acquirable upon complete conversion of such Holder’s Series H Convertible Preferred Stock (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Series H Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of common stock are to be determined for the grant, issue or sale of such Series H Purchase Rights (provided, however, that, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of common stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

Pro Rata Distributions. During such time as the Series H Convertible Preferred Stock is outstanding, if we declare or make any dividend or other distribution of our assets (or rights to acquire its assets) to holders of common stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) ( a “Series H Distribution”), then, in each such case, the Holder shall be entitled to participate in such Series H Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of the Series H Convertible Preferred Stock (without regard to any limitations on conversion hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Series H Distribution, or, if no such record is taken, the date as of which the record holders of shares of our common stock are to be determined for the participation in such Series H Distribution (provided, however, that, to the extent that the Holder’s right to participate in any such Series H Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Series H Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Series H Distribution to such extent) and the portion of such Series H Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

Fundamental Transactions. In the event of a Fundamental Transaction (as defined in the Series H Certificate of Designation) and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, or the acquisition of more than 50% of our outstanding common stock, the holders of the Series H Convertible Preferred Stock will be entitled to receive upon conversion of the Series H Convertible Preferred Stock the kind and amount of securities, cash or other property that the holders would have received had they converted the Series H Convertible Preferred Stock immediately prior to such Fundamental Transaction (without regard to the Beneficial Ownership Limitation).

Mandatory Redemption. If any shares of Series H Convertible Preferred Stock are outstanding at the end of the two (2) year term, then we shall promptly redeem all of such outstanding shares of Series H Convertible Preferred Stock on a pro rata basis among all of the Holders of Series H Convertible Preferred Stock commencing on the two-year anniversary of the original issue date in cash at a price per Series H Convertible Preferred Share equal to the sum of (x) 100% of the Series H Stated Value plus (y) all other amounts due in respect of the Series H Convertible Preferred Stock (if any).

Limited Voting Rights. Holders of the Series H Convertible Preferred Stock will not have any voting rights, except as described below or as otherwise required by law.

In any matter in which the Series H Convertible Preferred Stock may vote (as expressly provided herein or as may be required by law), each share of Series H Convertible Preferred Stock will be entitled to one vote per share.

•

alter or change adversely the powers, preferences or rights given to the Series H Convertible Preferred Stock or alter or amend the Series H Certificate of Designation;

The rules and procedures for calling and conducting any meeting of the holders of the Series H Convertible Preferred Stock (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules the Board (or a duly authorized committee of the Board), in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of our Charter, Bylaws, applicable law and any national securities exchange or other trading facility on which the Series H Convertible Preferred Stock may be listed or traded at the time.

Holders of the Series H Convertible Preferred Stock will not have any voting rights with respect to, and the consent of the holders of the Series H Convertible Preferred Stock is not required for, the taking of any corporate action, including any merger or consolidation involving us or a sale of all or substantially all of our assets, regardless of the effect that such merger, consolidation or sale may have upon the powers, preferences, voting power or other rights or privileges of the Series H Convertible Preferred Stock, except as described above.

No Preemptive Rights. No holders of the Series H Convertible Preferred Stock will, as holders of Series H Convertible Preferred Stock, have any preemptive rights to purchase or subscribe for the common stock or any other security.

Exclusion of Other Rights. The shares of the Series H Convertible Preferred Stock do not have any voting powers, preferences or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth in the Series H Certificate of Designation or in our Charter.

Series J Convertible Preferred Stock

Maturity. The Series J Convertible Preferred Stock matures one (1) year from the original issue date.

Ranking and Liquidation Preference. Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, prior and in preference to the common stock, holders of the Series J Convertible Preferred Stock shall be entitled to receive out of the assets available for distribution to stockholders an amount equal in cash to 100% of the aggregate Stated Value of $100.00 per share (the “Stated Value”) of all shares of Series J Convertible Preferred Stock held by such holder, and any other fees then due and owing thereon under the Certificate of Designation, and no more, and if the assets of the Company shall be insufficient to pay in full such amounts, then the entire assets to be distributed to the holders shall be ratably distributed among the holders in accordance with the respective amounts that would be payable on such shares if all amounts payable thereon were paid in full.

Dividends. The Certificate of Designation shall provide that dividends on the Series J Convertible Preferred Stock shall be paid in-kind (“PIK dividends”) in additional shares of Series J Convertible Preferred Stock based on the stated value of $100.00 per share and the annual dividend rate of 20.0% and a quarterly dividend rate of 5.0% (the “Quarterly Dividend Rate”). The PIK dividends will be paid on a quarterly basis for one year following the issuance of the Series J Convertible Preferred Stock payable to holders of the Series J Convertible Preferred of record at the close of business at the end of October 31, 2023, January 31, 2024, April 30, 2024 and July 31, 2024 (each a “Dividend Record Date”) at the Quarterly Dividend Rate. PIK dividends on each share of Series J Convertible Preferred Stock shall be paid three business days after each Dividend Record Date in additional fully paid and nonassessable, registered shares of Series J Convertible Preferred Stock in a number equal to the quotient obtained by dividing (A) the product obtained by multiplying (i) the Quarterly Dividend Rate and (ii) the stated value of $100.00 per share, by (B) the public offering price per Unit (equal to $60.00).

Conversion. The Series J Convertible Preferred Stock is convertible at any time at the option of the holder. Except as provided below, the Series J Convertible Preferred Stock is not convertible into or exchangeable for any other securities or property.

Conversion at Option of Holder. Each share of Series J Convertible Preferred Stock is convertible into shares of our common stock the conversion price of $4.37 per share of our common stock (the “Conversion Price”), which Conversion Price is subject to adjustment and is based on the closing price of our common stock on August 31, 2023.

Holders shall effect conversions of the Series J Convertible Preferred Stock by providing us a conversion notice (a “Notice of Conversion”), duly completed and executed. The Notice of Conversion must specify the number of shares of Series J Convertible Preferred Stock then held by the holder and the number of such shares which the holder is converting. To effect conversions of shares of Series J Convertible Preferred Stock, a holder shall not be required to surrender the certificate(s), if any, representing the shares of Series J Convertible Preferred Stock to us unless all of the shares of Series J Convertible Preferred Stock represented thereby are so converted, in which case such holder shall deliver the certificate representing such shares of Series J Convertible Preferred Stock promptly following the conversion date at issue. Shares of Series J Convertible Preferred Stock converted into our shares of common stock shall be canceled and shall not be reissued.

If, at any time while the Series J Convertible Preferred Stock is outstanding: we (A) pay a stock dividend or otherwise make a distribution or distributions payable in shares of our common stock or any other Common Stock Equivalents (as defined in the Certificate of Designation) (which, for avoidance of doubt, shall not include any shares of common stock issued by us upon conversion of the Series J Convertible Preferred Stock, or payment of a dividend on the Series J Convertible Preferred Stock) with respect to the then outstanding shares of common stock; (B) subdivide outstanding shares of common stock into a larger number of shares; (C) combine (including by way of a reverse stock split) outstanding shares of common stock into a smaller number of shares

or (D) issue, in the event of a reclassification of shares of the common stock, any shares of our capital stock, which we refer to collectively as the “Anti-Dilution Provisions”, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of common stock (excluding any treasury shares) outstanding immediately before such event and of which the denominator shall be the number of shares of common stock outstanding immediately after such event (excluding any treasury shares). Any adjustment made as a result of the Anti-Dilution Provisions shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination. All calculations will be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of the Anti-Dilution Provisions, the number of shares of common stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of common stock (excluding any treasury shares) issued and outstanding.

Whenever the Conversion Price is adjusted pursuant to any Anti-Dilution Provision, we will promptly deliver to each holder of Series J Convertible Preferred Stock a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Notwithstanding the foregoing in no event may the Conversion Price be less than the par value per share of Series J Convertible Preferred Stock.

Obligations Absolute. Subject to holder’s right to rescind a notice of conversion, our obligation to issue and deliver the shares of common stock upon conversion of Series J Convertible Preferred Stock in accordance with its terms are absolute and unconditional, irrespective of any action or inaction by a holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such holder or any other Person of any obligation to us or any violation or alleged violation of law by such holder or any other Person, and irrespective of any other circumstance which might otherwise limit our obligation to such holder in connection with the issuance of such shares of common stock. If we fail to deliver to a holder shares of common stock upon conversion by the Share Delivery Date (as defined in the Certificate of Designation) applicable to such conversion, we shall pay to such holder, in cash, as liquidated damages and not as a penalty, for each $250 of Stated Value of Series J Convertible Preferred Stock being converted, $2.50 per Trading Day (increasing to $5 per Trading Day on the third Trading Day after the Share Delivery Date and increasing to $10 per Trading Day on the sixth Trading Day after the Share Delivery Date) for each Trading Day after the Share Delivery Date until such Conversion Shares are delivered or Holder rescinds such conversion.

Buy-In on Failure to Timely Deliver Certificates Upon Conversion. If we fail to deliver to a holder the applicable certificate or certificates or to effect a delivery via DWAC, as applicable, by the Share Delivery Date (other than a failure caused by incorrect or incomplete information provided by the holder to us), and if after such Share Delivery Date the holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the holder’s brokerage firm otherwise purchases, shares of common stock to deliver in satisfaction of a sale by such holder of the Conversion Shares which the holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then we are obligated to (A) pay in cash to the holder (in addition to any other remedies available to or elected by the holder) the amount by which (x) the holder’s total purchase price (including any brokerage commissions) for the shares of common stock so purchased exceeds (y) the product of (1) the aggregate number of shares of common stock that such holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of the holder, either reissue (if surrendered) the shares of Series J Convertible Preferred Stock equal to the number of shares of Series J Convertible Preferred Stock submitted for conversion or deliver to the holder the number of shares of common stock that would have been issued if we had timely complied with our delivery requirements. For example, if a holder purchases shares of common stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series J Convertible Preferred Stock with respect to which the actual sale price (including any brokerage commissions) giving rise to such purchase obligation was a

total of $10,000 under clause (A) of the immediately preceding sentence, we would be required to pay such holder $1,000. The holder shall provide us written notice, within three Trading Days after the occurrence of a Buy-In, indicating the amounts payable to such holder in respect of such Buy-In together with applicable confirmations and other evidence reasonably requested by us. Nothing herein shall limit a holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect our failure to timely deliver certificates representing shares of common stock upon conversion of the shares of Series J Convertible Preferred Stock as required pursuant to the terms hereof; provided, however, that the holder shall not be entitled to both (i) require the reissuance of the shares of Series J Convertible Preferred Stock submitted for conversion for which such conversion was not timely honored and (ii) receive the number of shares of common stock that would have been issued if we had timely complied with applicable delivery requirements.

Reservation of Shares Issuable Upon Conversion. We have agreed that we will at all times reserve and keep available out of our authorized and unissued shares of common stock for the sole purpose of issuance upon conversion of the Series J Convertible Preferred Stock, free from preemptive rights or any other actual contingent purchase rights of Persons other than the holders of the Series J Convertible Preferred Stock, not less than such aggregate number of shares of the common stock as shall be issuable upon the conversion of all outstanding shares of Series J Convertible Preferred Stock. We have further agreed that all shares of common stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid, nonassessable and free and clear of all liens and other encumbrances.

Beneficial Ownership Limitation. Notwithstanding anything herein to the contrary, we shall not effect any conversion of the Series J Convertible Preferred Stock, and a Holder shall not have the right to convert any portion of the Series J Convertible Preferred Stock, to the extent that, after giving effect to the conversion set forth on the applicable Notice of Conversion, such Holder (together with such Holder’s Affiliates, and any Persons acting as a group together with such Holder or any of such Holder’s Affiliates (such Persons, “Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of common stock beneficially owned by such Holder and its Affiliates and Attribution Parties shall include the number of shares of common stock issuable upon conversion of the Series J Convertible Preferred Stock with respect to which such determination is being made, but shall exclude the number of shares of common stock which are issuable upon (i) conversion of the remaining, unconverted Series J Convertible Preferred Stock beneficially owned by such Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other of our securities subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Series J Convertible Preferred Stock) beneficially owned by such Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this section, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this section applies, the determination of whether the Series J Convertible Preferred Stock is convertible (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and of how many shares of Series J Convertible Preferred Stock are convertible shall be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder’s determination of whether the shares of Series J Convertible Preferred Stock may be converted (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and how many shares of the Series J Convertible Preferred Stock are convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to us each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this section and we shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this section, in determining the number of outstanding shares of common stock, a Holder may rely on the number of outstanding shares of common stock as stated in the most recent of the following: (i) our most recent periodic or annual report filed with the

Commission, as the case may be, (ii) a more recent public announcement by us or (iii) a more recent written notice by us or the Transfer Agent setting forth the number of shares of common stock outstanding. Upon the written or oral request (which may be via email) of a Holder, we within one (1) Trading Day confirm orally and in writing to such Holder the number of shares of common stock then outstanding. In any case, the number of outstanding shares of common stock shall be determined after giving effect to the conversion or exercise of our securities, including the Series J Convertible Preferred Stock, by such Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of common stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% (or, upon election by a Holder prior to the issuance of any shares of Series J Convertible Preferred Stock, 9.99%) of the number of shares of the common stock outstanding immediately after giving effect to the issuance of shares of common stock issuable upon conversion of Series J Convertible Preferred Stock held by the applicable Holder. A Holder, upon notice to us, may increase or decrease the Beneficial Ownership Limitation provisions of this section applicable to its Series J Convertible Preferred Stock; provided, that the Beneficial Ownership Limitation shall not in any event exceed 9.99% of the number of shares of the common stock outstanding immediately after giving effect to the issuance of shares of common stock upon conversion of this Series J Convertible Preferred Stock held by the Holder and the provisions of this section shall continue to apply. Any such increase will not be effective until the 61st day after such notice is delivered to us and shall only apply to such Holder and no other Holder. The Beneficial Ownership Limitation shall not be waived by us or the Holder and upon issuance of the Series J Convertible Preferred Stock by us, and the purchase thereof by the Holder, each of us and the Holder shall be deemed to acknowledge such limitation and to agree not to waive it. The provisions of this section shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this section to correct this section (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this Section shall apply to a successor holder of Series J Convertible Preferred Stock.

Subsequent Rights Offerings. In addition to any Anti-Dilution Adjustments described above, if at any time we grant, issue or sell any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of common stock or any class thereof (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of common stock acquirable upon complete conversion of such Holder’s Series J Convertible Preferred Stock (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of common stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of common stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

Pro Rata Distributions. During such time as the Series J Convertible Preferred Stock is outstanding, if we declare or make any dividend or other distribution of our assets (or rights to acquire its assets) to holders of common stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) ( a “Distribution”), then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of common stock acquirable upon complete conversion of the Series J Convertible Preferred Stock (without regard to any limitations on conversion hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of our common stock are to be determined for the participation in such Distribution (provided, however, that, to the extent that the

Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of common stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

Fundamental Transactions. In the event of a Fundamental Transaction (as defined in the Certificate of Designation) and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, or the acquisition of more than 50% of our outstanding common stock, the holders of the Series J Convertible Preferred Stock will be entitled to receive upon conversion of the Series J Convertible Preferred Stock the kind and amount of securities, cash or other property that the holders would have received had they converted the Series J Convertible Preferred Stock immediately prior to such Fundamental Transaction (without regard to the Beneficial Ownership Limitation).

Mandatory Redemption. If any shares of Series J Convertible Preferred Stock are outstanding at the end of the one (1) year term, then we shall promptly redeem all of such outstanding shares of Series J Convertible Preferred Stock on a pro rata basis among all of the Holders of Series J Convertible Preferred Stock commencing on the one-year anniversary of the original issue date in cash at a price per Series J Convertible Preferred Share equal to the sum of (x) 100% of the Stated Value plus (y) all other amounts due in respect of the Series J Convertible Preferred Stock (if any).

Limited Voting Rights. Holders of the Series J Convertible Preferred Stock will not have any voting rights, except as described below or as otherwise required by law.

In any matter in which the Series J Convertible Preferred Stock may vote (as expressly provided herein or as may be required by law), each share of Series J Convertible Preferred Stock will be entitled to one vote per share. So long as any shares of Series J Convertible Preferred Stock remain outstanding, we will not, without the consent or the affirmative vote of a majority of the outstanding shares of Series J Convertible Preferred Stock, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose:

•

alter or change adversely the powers, preferences or rights given to the Series J Convertible Preferred Stock or alter or amend the Series J Certificate of Designation;

•

increase the number of authorized shares of Series J Convertible Preferred Stock; or

•

enter into any agreement with respect to any of the foregoing.

The rules and procedures for calling and conducting any meeting of the holders of the Series J Convertible Preferred Stock (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules the Board (or a duly authorized committee of the Board), in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of the Certificate of Incorporation, Bylaws, applicable law and any national securities exchange or other trading facility on which the Series J Convertible Preferred Stock may be listed or traded at the time.

Holders of the Series J Convertible Preferred Stock will not have any voting rights with respect to, and the consent of the holders of the Series J Convertible Preferred Stock is not required for, the taking of any corporate action, including any merger or consolidation involving us or a sale of all or substantially all of our assets, regardless of the effect that such merger, consolidation or sale may have upon the powers, preferences, voting power or other rights or privileges of the Series J Convertible Preferred Stock, except as described above.

No Preemptive Rights. No holders of the Series J Convertible Preferred Stock will, as holders of Series J Convertible Preferred Stock, have any preemptive rights to purchase or subscribe for the common stock or any other security.

Exclusion of Other Rights. The shares of the Series J Convertible Preferred Stock do not have any voting powers, preferences or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth in the Certificate of Designation or in our Certificate of Incorporation.

Registration; Transfer. Pursuant to the terms of the Certificate of Designation, we are obligated to maintain an effective registration statement covering: (a) the issuance of shares of common stock issuable upon conversion of the Series J Convertible Preferred Stock and (b) the issuance of additional shares of Series J Convertible Preferred Stock pursuant to our obligation to pay PIK dividends, in each case, until such time as no Series J Convertible Preferred Stock (and no Warrants exercisable for shares of Series J Convertible Preferred Stock) remain outstanding, unless there is available an exemption from, or a transaction not subject to, the registration requirements of the Securities Act that covers the issuance of the Series J Convertible Preferred Stock and the shares of common stock issuable upon conversion of such shares of Series J Convertible Preferred Stock.

Book-Entry Procedures. DTC will act as securities depositary for the Series J Convertible Preferred Stock offered hereunder. With respect to the Series J Convertible Preferred Stock offered hereunder, we will issue one or more fully registered global securities certificates in the name of DTC or DTC’s nominee. These certificates will represent the total aggregate number of shares of Series J Convertible Preferred Stock. We will deposit these certificates with DTC or a custodian appointed by DTC. We will not issue certificates to you for the shares of Series J Convertible Preferred Stock that you purchase, unless DTC’s services are discontinued as described below.

Title to book-entry interests in the Series J Convertible Preferred Stock will pass by book-entry registration of the transfer within the records of DTC in accordance with its procedures. Book-entry interests in the securities may be transferred within DTC in accordance with procedures established for these purposes by DTC. Each person owning a beneficial interest in shares of the Series J Convertible Preferred Stock must rely on the procedures of DTC and the participant through which such person owns its interest to exercise its rights as a holder of the Series J Convertible Preferred Stock.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants (“Direct Participants”) deposit with DTC. DTC also facilitates the settlement among Direct Participants of securities transactions, such as transfers and pledges in deposited securities through electronic computerized book-entry changes in Direct Participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. Access to the DTC system is also available to others such as securities brokers and dealers, including the placement agent, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The rules applicable to DTC and its Direct and Indirect Participants are on file with the SEC.

When you purchase shares of Series J Convertible Preferred Stock within the DTC system, the purchase must be by or through a Direct Participant. The Direct Participant will receive a credit for the Series J Convertible Preferred Stock on DTC’s records. You will be considered to be the “beneficial owner” of the Series J Convertible Preferred Stock. Your beneficial ownership interest will be recorded on the Direct Participants and Indirect Participants’ records, but DTC will have no knowledge of your individual ownership. DTC’s records reflect only the identity of the Direct Participants to whose accounts shares of Series J Convertible Preferred Stock are credited.

You will not receive written confirmation from DTC of your purchase. The Direct Participants or Indirect Participants through whom you purchased the Series J Convertible Preferred Stock should send you written confirmations providing details of your transactions, as well as periodic statements of your holdings. The Direct Participants and Indirect Participants are responsible for keeping an accurate account of the holdings of their customers like you.

Transfers of ownership interests held through Direct Participants and Indirect Participants will be accomplished by entries on the books of Direct Participants and Indirect Participants acting on behalf of the beneficial owners.

The laws of some states may require that specified purchasers of securities take physical delivery of shares of Series J Convertible Preferred Stock in definitive form. These laws may impair the ability to transfer beneficial interests in the global certificates representing the Series J Convertible Preferred Stock.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

We understand that, under DTC’s existing practices, in the event that we request any action of the holders, or an owner of a beneficial interest in a global security, such as you, desires to take any action that a holder is entitled to take under our Certificate of Incorporation (including the Certificate of Designation designating the Series J Convertible Preferred Stock), DTC would authorize the Direct Participants holding the relevant shares to take such action, and those Direct Participants and any Indirect Participants would authorize beneficial owners owning through those Direct Participants and Indirect Participants to take such action or would otherwise act upon the instructions of beneficial owners owning through them.

Any redemption notices with respect to the Series J Convertible Preferred Stock will be sent to DTC or its nominee. If less than all of the outstanding shares of Series J Convertible Preferred Stock are being redeemed, DTC will reduce each Direct Participant’s holdings of shares of Series J Convertible Preferred Stock in accordance with its procedures.

In those instances where a vote is required, neither DTC nor its nominee will consent or vote with respect to the shares of Series J Convertible Preferred Stock. Under its usual procedures, DTC would mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns DTC’s or its nominee’s consenting or voting rights to those Direct Participants whose accounts the shares of Series J Convertible Preferred Stock are credited to on the record date, which are identified in a listing attached to the omnibus proxy.

Dividends on the Series J Convertible Preferred Stock are made directly to DTC (or its successor, if applicable). DTC’s practice is to credit participants’ accounts on the relevant payment date in accordance with their respective holdings shown on DTC’s records unless DTC has reason to believe that it will not receive payment on that payment date.

Payments by Direct Participants and Indirect Participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name.” These payments will be the responsibility of the participant and not of DTC, us or any agent of ours. DTC may discontinue providing its services as securities depositary with respect to the Series J Convertible Preferred Stock at any time by giving reasonable notice to us. Additionally, we may decide to discontinue the book-entry only system of transfers with respect to the Series J Convertible Preferred Stock. In that event, we will print and deliver certificates in fully registered form for the Series J Convertible Preferred Stock. If DTC notifies us that it is unwilling to continue as securities depositary, or it is unable to continue or ceases to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed by us within 90 days after receiving such notice or becoming aware that DTC is no longer so registered, we will

issue the Series J Convertible Preferred Stock in definitive form, at our expense, upon registration of transfer of, or in exchange for, such global security.

According to DTC, the foregoing information with respect to DTC has been provided to the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

Global Clearance and Settlement Procedures. Initial settlement for the Series J Convertible Preferred Stock will be made in immediately available funds. Secondary market trading among DTC’s participants occurs in the ordinary way in accordance with DTC’s rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System.

Direct Registration System. The Series J Convertible Preferred Stock will be registered in book-entry form through the Direct Registration System (the “DRS”). The DRS is a system administered by DTC pursuant to which the depositary may register the ownership of uncertificated shares, which ownership shall be evidenced by periodic statements issued by the depositary to the holders of shares of Series J Convertible Preferred Stock entitled thereto. This direct registration form of ownership allows investors to have securities registered in their names without requiring the issuance of a physical stock certificate, eliminates the need for you to safeguard and store certificates and permits the electronic transfer of securities to effect transactions without transferring physical certificates.

Anti-Takeover Provisions of Delaware Law and Our Governing Documents

Delaware Law

We are incorporated in the State of Delaware. As a result, we are subject to Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the time that such stockholder became an interested stockholder, with the following exceptions:

•

before such time, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (1) by persons who are directors and also officers and (2) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

•

at or subsequent to such time, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

In general, Section 203 defines a “business combination” to include the following:

•

any merger or consolidation involving the corporation or a direct or indirect majority-owned subsidiary of the corporation and the interested stockholder;

•

any sale, lease, mortgage, pledge transfer, or other disposition of the assets of the corporation or direct or indirect majority-owned a subsidiary of the corporation to or with the interested stockholder, which assets have an aggregate value equal to 10% or more of the fair value of the assets on a consolidated basis or the aggregate market value of the outstanding stock of the corporation;

•

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation or a direct or indirect majority-owned subsidiary of the corporation of any stock of the corporation or subsidiary to the interested stockholder;

•

any transaction involving the corporation or direct or indirect majority-owned subsidiary of the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation or the subsidiary beneficially owned by the interested stockholder; or

•

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation or direct or indirect majority-owned subsidiary of the corporation.

In general, under Section 203 defines an “interested stockholder” include an entity or person (other than the corporation any direct or indirect majority-owned subsidiary of the corporation) who, together with the person’s affiliates and associates, beneficially owns, 15% or more of the outstanding voting stock of the corporation. A Delaware corporation may “opt out” of these provisions with an express provision in its certificate of incorporation. Since we have not opted out of Section 203, Section 203 may discourage or prevent mergers or other takeover or change of control attempts of us.

Undesignated Preferred Stock

The ability to authorize undesignated preferred stock makes it possible for our Board to issue one or more series of preferred stock with voting or other rights or preferences. Thus, our Board could authorize the issuance of shares of preferred stock that have priority over our common stock with respect to dividends or rights upon liquidation or with terms and conditions that could have the effect of delaying, deferring or preventing a transaction or a change of control of our Company that might involve a premium price for holders of our common stock or otherwise be in their best interests.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the Board or a committee of the Board.

Stockholder Action by Written Consent; Special Meetings of Stockholders

Our stockholders may take action by written consent in lieu of a meeting as provided in our Bylaws. Our Bylaws provide that certain procedures, including notifying the Board and awaiting a record date, must be followed for stockholders to act by written consent. A special meeting of our stockholders may be called only by our Board, the Chairman of the Board, the Chief Executive Officer or the President. A special meeting may also be called at the request of stockholders holding a majority of the aggregate number of shares of our capital stock issued and outstanding and entitled to vote at that meeting (subject to certain timeliness and content requirements of the demand).

Amendment of Charter and Bylaws

Our Charter may be amended by the affirmative vote of a majority of the aggregate number of shares of each class of our capital stock issued and outstanding after a resolution of our Board declaring the advisability of such amendment has been adopted in accordance with Delaware law. Our Bylaws may be amended by the affirmative vote of a majority of the aggregate number of shares of each class of our capital stock issued and outstanding (and entitled to vote on the subject matter) present in person or represented by proxy at a meeting of stockholders provided that notice thereof is stated in the written notice of the meeting. Our Bylaws may also be amended by a majority of the Board in accordance with Delaware law and our Charter, except that certain sections of our

Bylaws (including but not limited to certain provisions regarding special meetings, voting, officers and approval of securities issuances) require either the affirmative vote of two-thirds of the persons then serving as directors on the Board or our stockholders.

Forum Selection

Unless the Board acting on behalf of the Company selects an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another state court located within the State of Delaware or, if no court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware) shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to the Company or our stockholders, (iii) any action asserting a claim against the Company or any of our directors, officers or other employees arising pursuant to any provision of the DGCL, our Charter or our Bylaws or (iv) any action asserting a claim against the Company or any of our directors, officers or other employees governed by the internal affairs doctrine of the State of Delaware.

DESCRIPTION OF THE PRIVATE PLACEMENT

On December 6, 2023, we entered into the Purchase Agreement with the Purchaser/Selling Stockholder, pursuant to which we issued to the Selling Stockholder, (i) in a registered direct offering, 331,000 shares of our Common Stock (the “Shares”), and Pre-Funded Warrants to purchase 779,940 shares of our Common Stock with an exercise price of $0.001 per share, and (ii) in the concurrent Private Placement, we issued the Common Warrants to purchase an aggregate of up to 2,221,880 Common Warrant Shares with an exercise price of $1.23. Such registered direct offering and concurrent Private Placement are referred to herein as the “Transactions.” The combined purchase price for one Share and two Common Warrants was $1.23, and the combined purchase price for one Pre-Funded Warrant and two Common Warrants was $1.229.

We received aggregate gross proceeds from the Transactions of approximately $1.4 million, before deducting fees to the Placement Agent and other estimated offering expenses payable by us. The Shares, the Pre-Funded Warrants and the shares of Common Stock issuable upon exercise of the Pre-Funded Warrants (the “Pre-Funded Warrant Shares”) were offered by us pursuant to a shelf registration statement on Form S-3 (File No. 333-266852), which was declared effective on August 24, 2022. The Common Warrants and the Common Warrant Shares issued in the Private Placement were not registered under the Securities Act. Rather the Common Warrants and the Common Warrant Shares were issued pursuant to the exemption from registration provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder. The Common Warrants are exercisable commencing on the effective date of stockholder approval for the issuance of the shares of our Common Stock issuable upon exercise of the Common Warrants (the “Stockholder Approval Date”) and will expire on the fifth anniversary of the Stockholder Approval Date. The Pre-Funded Warrants were immediately exercisable upon issuance and may be exercised at any time until all of the Pre-Funded Warrants are exercised in full.

Pursuant to the terms of the Purchase Agreement, until 30 days following the closing of the Transactions, we have agreed not to issue (or enter into any agreement to issue) any shares of our Common Stock or Common Stock Equivalents (as defined in the Purchase Agreement), subject to certain exceptions. In addition, subject to certain exceptions, we are prohibited from effecting or entering into an agreement to effect any issuance by us or any of our subsidiaries of Common Stock or Common Stock Equivalents (or a combination of units thereof) involving a Variable Rate Transaction (as such terms are defined in the Purchase Agreement) until 180 days following the closing date of the Transactions, which was December 8, 2023. Further, our Chief Executive Officer and each of our directors and executive officers have entered into lock-up agreements pursuant to which each of them has agreed not to, for a period of 30 days from the closing of the Transactions, offer, sell, transfer or otherwise dispose of our securities, subject to certain exceptions. In addition, from the date of the Purchase Agreement until the date that is twelve (12) months after the Stockholder Approval Date, upon any issuance by us or any of our subsidiaries of Common Stock, Common Stock Equivalents or preferred stock for cash consideration, Indebtedness (as defined in the Purchase Agreement) or a combination of securities thereof (a “Subsequent Financing”), the Purchaser will have the right to participate in up to an amount of the Subsequent Financing equal to 33% of the Subsequent Financing on the same terms, conditions and price provided for in the Subsequent Financing.

The exercise price of the Pre-Funded Warrants and the Common Warrants, and the number of Pre-Funded Warrant Shares and Common Warrant Shares, will be subject to adjustment in the event of any stock dividend or split, reverse stock split, recapitalization, reorganization or similar transaction, as described in the Pre-Funded Warrants or Common Warrants. Subject to certain exceptions, the Common Warrants provide for adjustment of the exercise price, if we or any of our subsidiaries, as applicable, sell or grant any right to reprice, or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any shares of our Common Stock or Common Stock Equivalents, at an effective price per share that is less than the exercise price then in effect (such lower price, the “Base Share Price” and such issuances collectively, a “Dilutive Issuance”). In the event a Dilutive Issuance occurs, the exercise price shall be reduced to equal the Base Share Price.

The Pre-Funded Warrants and Common Warrants are exercisable on a “cashless” basis in certain circumstances.

We have agreed to file a registration statement to register the resale of the Common Warrant Shares within 30 days of the date of the Purchase Agreement and to use our commercially reasonable efforts to cause such registration statement to become effective within 121 days following the closing date of the Transactions (or within 181 days following the closing date of the offering if the SEC informs us that it intends to review such registration statement). The Purchaser has agreed not to resell or distribute the Common Warrants or the Common Warrant Shares to the public except pursuant to an effective registration statement under the Securities Act or an exemption therefrom.

Maxim Group LLC acted as the Placement Agent on a “reasonable best efforts” basis, in connection with the Transactions pursuant to the Placement Agency Agreement by and between us and the Placement Agent. Pursuant to the Placement Agency Agreement, the Placement Agent was paid a cash fee of 7% of the aggregate gross proceeds paid to us for the securities sold in the Transactions and reimbursement of certain out-of-pocket expenses up to $40,000.

SELLING STOCKHOLDER

The shares of our Common Stock being offered by the Selling Stockholder are those issuable to the Selling Stockholder upon exercise of the Common Warrants. For additional information regarding the issuances of the Common Warrants and the Common Warrant Shares, see “Description of the Private Placement” elsewhere in this prospectus. We are registering the shares of our Common Stock in order to permit the Selling Stockholder to offer the shares of our Common Stock for resale from time to time. Except for the ownership of shares of our Common Stock, the Common Warrants, the Pre-Funded Warrants, the Pre-Funded Warrant Shares and the Common warrant Shares purchased in the Transactions, the Selling Stockholder has not had any material relationship with us within the past three years.

The following table sets forth certain information with respect to the Selling Stockholder, including (i) the number of shares of our Common Stock beneficially owned by the Selling Stockholder, including and securities exercisable for shares of our Common Stock, prior to this offering without regard to any beneficial ownership limitations contained in the Common Warrants and Pre-Funded Warrants (as specified below), (ii) the number of shares of our Common Stock being offered by the Selling Stockholder pursuant to this prospectus and (iii) the Selling Stockholder’s beneficial ownership after completion of this offering assuming the sale of all of the shares of our Common Stock covered by this prospectus. The registration of the shares of our Common Stock issuable to the Selling Stockholder upon the exercise of the Common Warrants does not necessarily mean that the Selling Stockholder will sell all or any of such shares, but the number of shares and percentages set forth in the final two columns below assume that all shares of our Common Stock being offered by the Selling Stockholder are sold.

The table is based on information supplied to us by the Selling Stockholder, with beneficial ownership and percentage ownership determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to shares of stock. This information does not necessarily indicate beneficial ownership for any other purpose. In computing the number of shares beneficially owned by the Selling Stockholder and the percentage ownership of the Selling Stockholder, shares of our Common Stock subject to the Common Warrants and the Pre-Funded Warrants held by the Selling Stockholder that are exercisable within 60 days after December 15, 2023, are deemed outstanding. The percentage of beneficial ownership after this offering is based on 3,415,903 shares of our Common Stock outstanding on December 15, 2023.

This prospectus covers the resale of 2,221,880 shares of our Common Stock that may be sold or otherwise disposed of by the Selling Stockholder. Such shares of our Common Stock are issuable to the Selling Stockholder upon the exercise of the Common Warrants. Furthermore, the Common Warrants will not be exercisable until the Stockholder Approval Date and will expire on the fifth anniversary of the Stockholder Approval Date. For purposes of this Selling Stockholder table, we have assumed that the Stockholder Approval Date will occur within 60 days after December 15, 2023.

The Common Warrants have an exercise price of $1.23 per share. See “Description of the Private Placement” above for a more complete description of the Common Warrants. Under the terms of the Common Warrants, the Selling Stockholder may not exercise the Common Warrants to the extent such exercise would cause such Selling Stockholder, together with its affiliates and attribution parties, to beneficially own a number of shares of Common Stock that would exceed 9.99%, as applicable, of our then outstanding Common Stock following such exercise, excluding for purposes of such determination shares of Common Stock issuable upon exercise of such Common Warrants that have not been exercised. The number of shares in the second and fourth columns do not reflect this limitation. The Selling Stockholder may sell all, some or none of their shares in this offering. See “Plan of Distribution.”

Consists of (i) 331,000 shares of Common Stock; (ii) 779,940 shares issuable upon exercise of the Pre-Funded Warrants; and (iii) 2,221,800 Common Warrant Shares issuable upon the exercise of the Common Warrants. The Pre-Funded Warrants are subject to a beneficial ownership limitation of 9.99% of the number of shares of our Common Stock outstanding and the Common Warrants are subject to a beneficial ownership limitation of 4.99% of the number of shares of our Common Stock outstanding, which in each case restricts the Selling Stockholder from exercising that portion of the warrants that would result in the Selling Stockholder and its affiliates owning, after exercise, a number of shares of Common Stock in excess of the beneficial ownership limitation. The number of shares set forth in the above table does not reflect the application of this limitation.

PLAN OF DISTRIBUTION

The Selling Stockholder of the securities and any of its pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the Nasdaq Capital Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Stockholder may use any one or more of the following methods when selling securities:

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•

block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•

an exchange distribution in accordance with the rules of the applicable exchange;

•

privately negotiated transactions;

•

settlement of short sales;

•

in transactions through broker-dealers that agree with the Selling Stockholder to sell a specified number of such securities at a stipulated price per security;

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•

a combination of any such methods of sale; or

•

any other method permitted pursuant to applicable law.

The Selling Stockholder may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholder may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholder (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the Selling Stockholder may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholder may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholder and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

We are required to pay certain fees and expenses incurred by us incident to the registration of the securities. We have agreed to indemnify the Selling Stockholder against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholder without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for us to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the Selling Stockholder or any other person. We will make copies of this prospectus available to the Selling Stockholder and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Item 14.

Indemnification of Directors and Officers.

Section 145 of the Delaware General Corporation Law (the “DGCL”) authorizes and empowers a Delaware corporation to indemnify its directors, officers, employees and agents against liabilities incurred in connection with, and related expenses resulting from, any claim, action or suit brought against any such person as a result of his or her relationship with the corporation, provided that such persons acted in good faith and in a manner such person reasonably believed to be in, and not opposed to, the best interests of the corporation in connection with the acts or events on which such claim, action or suit is based. Section 145 of the DGCL also authorizes corporations to purchase and maintain insurance on behalf of such persons so indemnified. The finding of either civil or criminal liability on the part of such person in connection with such acts or events is not necessarily determinative of the question of whether such person has met the required standard of conduct and is, accordingly, entitled to be indemnified.

Section 102(b)(7) of the DGCL enables a corporation in its certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director to the corporation or its stockholders of monetary damages for violations of the directors’ fiduciary duty of care, except (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL (providing for liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions) or (iv) for any transaction from which a director derived an improper personal benefit.

The Company’s Restated Certificate of Incorporation, as amended (the “charter”), provides that, to the extent permitted by applicable law, the registrant’s directors shall not be personally liable to the registrant or its stockholders for monetary damages for any breach of fiduciary duty as directors of the registrant. The charter eliminates the personal liability of directors to the fullest extent permitted by the DGCL. The Company’s Eighth Amended and Restated Bylaws (the “bylaws”) provide that each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the registrant shall be indemnified and held harmless by the registrant to the fullest extent authorized by the DGCL, against all costs, charges, expenses, liabilities and losses (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith, and such indemnification shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of his or her heirs, executors and personal or legal representatives. The Company has also obtained liability insurance for its officers and directors and has entered into indemnification agreements with its directors and officers.

II-1

The foregoing statements are subject to the provisions of Sections 145 and 102(b)(7) of the DGCL, the Company’s bylaws and the Company’s charter, which bylaws and charter have been filed as exhibits to this registration statement.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 15.

Recent Sales of Unregistered Securities.

On December 6, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with a single institutional investor (the “Purchaser”), pursuant to which the Company issued to the Purchaser, (i) in a registered direct offering, 331,000 shares of the Company’s common stock (the “Shares”), par value $0.001 per share (“Common Stock”), and pre-funded warrants to purchase 779,940 shares of Common Stock (the “Pre-Funded Warrants”) with an exercise price of $0.001 per share, and (ii) in a concurrent private placement, warrants (the “Common Warrants”) to purchase an aggregate of 2,221,880 shares of Common Stock (the “Common Warrant Shares”) with an exercise price of $1.23.

The combined purchase price for one share of Common Stock and one warrant was $4.625 and the combined purchase price for one pre-funded warrant and one warrant was $4.624 (on a pre-2023 Reverse Stock Split basis).

The warrants and the shares of Common Stock issuable upon exercise of the warrants were offered pursuant to the exemption from registration provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder.

In June 2020, the Company issued warrants to purchase 432,000 shares of Common Stock, with an exercise price of $12.88 per share (on a pre-2023 Reverse Stock Split basis).

The Company received aggregate gross proceeds in the offerings of approximately $6.9 million. The warrants and the shares of Common Stock issuable upon exercise of the warrants were offered pursuant to the exemption from registration provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder.

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

That, for the purpose of determining liability under the Securities Act to any purchaser:

(A) Each prospectus filed by a Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

II-3

That, for purposes of determining any liability under the Securities Act, each filing of Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by a Registrant of expenses incurred or paid by a director, officer or controlling person of a Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, that Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
